Function Documentation

void SystemCoreClockUpdate ( void  )

Updates the SystemCoreClock variable.

It must be called whenever the core clock is changed during program execution. SystemCoreClockUpdate() evaluates the clock register settings and calculates the current core clock. This function must be called when user does not want to use clock manager component. If clock manager is used, the CLOCK_SYS_GetFreq function must be used with CORE_CLOCK parameter.

Definition at line 138 of file system_S32K148.c.

void SystemInit ( void  )

Setup the microcontroller system.

Typically this function configures the oscillator that is part of the microcontroller device. For systems with variable clock speed it also updates the variable SystemCoreClock. SystemInit is called from startup_device file.

Definition at line 82 of file system_S32K148.c.

void SystemSoftwareReset ( void  )

Software Resets the microcontroller system.

This function is used to software reset the microcontroller

Variable Documentation

uint32_t SystemCoreClock

System clock frequency (core clock)

The system clock frequency supplied to the SysTick timer and the processor core clock. This variable can be used by the user application to setup the SysTick timer or configure other parameters. It may also be used by debugger to query the frequency of the debug timer or configure the trace clock speed SystemCoreClock is initialized with a correct predefined value.
